Elon Musk, eat your heart out.

As first reported by Yahoo, Mark Zuckerberg, CEO of Meta — the parent company of Instagram, Facebook and WhatsApp — would eat a wild amount of McDonald’s to help him “offset all the activity” in his newfound hobby of martial arts.

Last week, in a reply to the official McDonald’s account on Threads, Zuckerberg said his order would include 20 Chicken McNuggets, a Quarter Pounder, an Oreo McFlurry, an apple pie and a large order of french fries. Oh, and he would also take some “side cheeseburgers for later.”

Now that the billionaire is friendly with multiple professional fighters, such as MMA star Israel Adesanya, he regularly trains with them in places near and far — including  Lake Tahoe and San Jose’s Guerrilla Jiu-Jitsu. After Zuckerberg posted his order on Threads, MMA fighter Mike Davis chimed in with a reply that said, “You’re in camp! No Mcdonald’s,” followed by a laughing emoji.

Zuckerberg made it clear that he is not cutting weight at the moment. How could he? He’s training to take down Tesla CEO and newfound nemesis Elon Musk. The fight, which has no confirmed date yet, will apparently be streamed on X, Musk’s platform formerly known as Twitter. Zuckerberg said he needs around 4,000 calories a day to help fuel his body during training, according to his reply to Davis. Zucks is certainly talking the talk when it comes to fitting into the MMA crowd.

Perhaps Musk will disclose his own McDonald’s order — which probably comes with a Diet Coke.
